I'd like to preface by saying I'm not much of an expert with OSX or with the finer aspects of computers such as placing things in a directory through the terminal. With that in mind, I have followed the instructions from the add-on packages section of the content page of the wiki. I have therefore ran these two lines:

I've let it run for a whole night and it just kept reloading the last 7 lines, starting with the credit bytes line. Needless to say, the voices don't work in the game (and yes, I did turn the voice sound up!)

It would be substantially simpler to make a separate applescript that people should drop improvements onto, that has to be kept next to the UQM application.

That would be more secure than providing a symlink or alias, and also much easier (one could do it in Automator)… hmm. Maybe I'll make one. It'll just check if the file was .uqm and then if it was copy it over to the appropriate location.
